Abstract: Nitric oxide formation in gas turbine combustion depends on four key factors: flame stabilization, heat transfer, fuel–air mixing and combustion instability. The design of modern gas turbine burners requires delicate compromises between fuel efficiency, emissions of oxides of nitrogen (NOx) and combustion stability. Burner designs allowing substantial NOx reduction are often prone to combustion oscillations. These oscillations also change the NOx fields. Being able to predict not only the main species field in… Show more

“…The NSCBC boundaries behave like a first-order low-pass filter and have cut-off frequencies proportional to the relaxation coefficient. All walls are modeled using a logarithmic wall-law condition [59] and side boundaries of the combustion chamber are considered axi-periodic.…”

“…It is a cell-vertex/finite element code, explicit in time, which solves the compressible Navier-Stokes equations on unstructured meshes for the conservative variables (mass density, momentum and total energy). AVBP is dedicated to Large-Eddy Simulations and Direct Numerical Simulations and has been widely used and validated in the past years in all kinds of configurations (Schönfeld and Rudgyard, 1999;Moureau et al, 2005;Schmitt et al, 2007;Prière et al, 2004;Roux et al, 2008;Mendez and Nicoud, 2008b). The numerical scheme is the TTGC (Twostep Taylor Galerkin C) scheme (Colin and Rudgyard, 2000): this essentially non dissipative scheme was specifically developed to handle unsteady turbulent flows with unstructured meshes.…”

“…To properly reproduce the effect of the subgrid scale interaction between turbulence and chemistry, the so-called efficiency function, E [18] is introduced to recover the turbulent flame speed. The DTFLES model has been applied successfully to several configurations (premixed and partially premixed) and more details can be found in [19].…”
